diff mercurial/changegroup.py @ 23748:4ab66de46a96

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
bundle: when verbose, show what takes up the space in the generated bundle This is kind of similar to the debugbundle command but gives summarized actual uncompressed number of bytes when creating the bundle. The numbers are as usable as the bundle format is efficient. Hopefully bundle2 will make it a better indicator of actual entropy. This is useful when accepting pull requests to assess whether the repo size increase seems reasonable for the diff before pushing stuff upstream, It has helped me catching large files that should have been committed as largefiles but was committed as regular files in intermediate changesets. This output doesn't combine well with debug output so we only enable it when verbose without debug.
